T30 With 3" Stroke Black Brake Chamber

Primarily installed on the front axle of vehicles, this product features a black exterior design and offers a stroke specification of 3 inches (76 mm). It utilizes an extended pushrod design to accommodate various vehicle models, ensuring broad compatibility. Its core components include a high-grade rubber diaphragm capable of maintaining stable performance across varying pressure levels. Furthermore, the diaphragm exhibits exceptional thermal resistance, enabling the product to operate effectively in environments ranging from -40°C to +80°C—a capability particularly critical for meeting the demands of ultra-low-temperature conditions down to -40°C.
In terms of technical specifications, the product has a maximum operating air pressure rating of 150 PSI (approximately 10 Bar). The air port threads are available in two specifications—3/8" or M16—to seamlessly integrate with the pneumatic systems of different vehicle models. To enhance durability, the housing has undergone a rigorous 72-hour salt spray test, demonstrating robust corrosion resistance. Throughout the manufacturing process, the factory employs specialized high/low-temperature test benches, endurance testers, thickness gauges, and surface roughness testers to ensure strict adherence to quality standards. Upon request, the manufacturer can provide batch-specific reports detailing high/low-temperature and endurance test results, and offers a 12-month quality warranty.
The product supports extensive customization options, including modifications to surface finishes, pushrod lengths, and yoke styles to meet specific requirements. Additional services include laser engraving, custom labeling, and various packaging solutions—such as individual polybags or full-color retail boxes—as well as neutral bulk packaging options designed to help users maintain and reinforce their brand identity. Prior to mass production, technical drawings are provided for client confirmation to ensure manufacturing consistency; the manufacturer also welcomes custom orders based on provided samples. For shipment, the product is supplied in a "park brake engaged" state; the air inlet is fitted with a protective thread plug, the pushrod is covered by a color-coded protective mesh sleeve, and the entire unit is enclosed in a protective bag during packing to safeguard its condition throughout transit.
